Setting Up Identity Owner Notifications for Amazon SES Sending Authorization

When a delegate sender sends emails on your behalf, bounces and complaints that those emails generate count toward the delegate sender's bounce and complaint metrics rather than your own. However, if you want to be informed of these email-sending outcomes, you can set up notifications by email or by Amazon SNS notifications just as you would for any other identity. Follow the procedures in Monitoring Using Amazon SES Notifications.

Delegate senders can set up their own Amazon SNS notifications for the identities that you have authorized them to use, although only you, the identity owner, can control whether feedback can be directly forwarded to your identity via email.
